Abstract : The Service Oriented Architecture (Soa) paradigm supports the assembly of atomic services to create applications that implement complex business processes. Assem- bly is accomplished by service orchestrations defined by Soa architects. The Adore frame- work allows Soa architects to model complex orchestrations of services by composing mod- els of smaller orchestrations involving subsets of services. The smaller orchestrations are called orchestration fragments and encapsulates new concerns. Adore is then used to weave fragments into existing application models. This demonstration illustrates how the Adore framework can be used to model a Soa using fragments composition. We illustrate it using several implemented case studies.
